DOOR CHECK AND HOLDER.

Specification of Letters Patent.

Application filed December 20, 1909.

Serial No. 534,025.

To all whom it may concern:

Be it known that I, OSCAR E. HENDRICKS, a citizen of the United States,residing at Ottumwa, in the county of Wapello and State of Iowa,have'invented a new and useful Door Check and Holder, of which thefollowing is a specification.

This invention has relation to door checks and holders and it consistsin the novel construction and arrangement of its parts as hereinaftershown and described.

The object of the invention is to provide a simple, ornamental andeffective device for checking the swinging movement of a door or similarstructure and for holding the same in an open position when such isdesired.

With the above object in view, the structure includes a tubular postadapted to be attached to a wash board or other fixed support and havingan outer end portion of peculiar configuration. A socket member isprovided for insertion in the side of the door or swinging structure andcarries in its interior a knob of peculiar configuration which serves asa buckle adapted to operate against the end of the said post. Flexiblegaskets and washers are provided in combination with the other elementsof the structure which serve as means for breaking the force of impactwhen the parts come together and also for the purpose of deadening thenoise incident to such impact.

In the accompanying drawing: Figure 1 is a view of the door check andholder showing a post in side elevation and the receiving socket memberin section. Fig. 2 is a vertical sectional view of the members of thedoor check and holder.

The door check and holder consists of a tubular post 1 which is adaptedto be secured to a washboard or other fixed support by means of a screw2 passing through its face and with its head within the said post. Thehead of the post 1 is provided with one or more longitudinally disposedslits or incisions 3 and the outer extremity of the said post isslightly conical or pointed as at 4. At the outer end of the conicalportion 4 an inturned edge 5 is'provided, the object of which will behereinafter explained. In the vicinity of the outer end of the post 1,an annular ring 6 is formed of relatively small diameter and spaced fromthe said ring 6 is formed an annular ring 7 of relatively largediameter. The ring 7 is located nearer the base of the post than thering 6.

A socket member 8 is adapted to be inserted in the face of a door orother swinging structure and is provided with an annular flange 9 havinga return bent portion 10. A knob 11 is provided with a screw shank 12which passes through the inner end of the socket member 8 and is adaptedto enter the wood or other material of which the swinging structure iscomposed and serves as means for securely holding the said socket memberin position upon the said swinging structure. The knob 11 is providedwith an annular shoulder 12 located at a point approximately midwaybetween its ends and that end of the knob 11 located nearest the flange9 of the socket 8 is formed into a globular head 13. The materialbetween the head 13 and shoulder 12 is re duced, forming a neck 14. Aflexible washer 15 of rubber or similar material surrounds the neckportion 14 of the knob 11 and rests at one side against the annularshoulder 12 of the said knob. A flexible gasket of rubber or similarmaterial is fixed to the inner wall of the socket member 8 in thevicinity of the annular flange 9 and in a vertical plane in advance ofor coincident with the vertical plane of the outermost portion of thehead 13 of the said knob 11. The diameter of the opening between theopposite edges of the flange 5 formed at the outer end of the post 1 isslightly less than the diameter of the head portion 13 of the knob 11.Consequently as the said head 13 enters the opening bounded by theflange 5, the outer end. of the post 1 is slightly expanded or spread atthe incision 3 and when the flange 5 passes to a plane which traversesthe reduced neck portion 14 of the knob 11 by in herent resiliency, theopposite side portions of the post 1 swing toward each other and closeslightly about the reduced neck portion 14 of the said knob 11. When theswinging structure is swung toward the said post 1, the end of the saidpost enters the socket member 8 and the head of the knob 11 enters theend of the said post in the manner indicated. As the ring 6 passes bythe gasket 16, the said ring comes in contact with the gasket and theforce of impact of the approaching parts is reduced and when the ring 6passes beyond the gasket 16, the said gasket enters the space betweenthe rings Patented Mar. 15, 1910.

6 and 7 and surrounds the outer portion of the post 1. YVhen the end ofthe conical portion l comes in contact with the washer 15, the socketmember 8 is checked against further movement toward the post 1 and thesaid washer 15 serves as a bumper which also breaks the force of impactof the parts as they are brought together. By reason of the fact thatthe washer 15 and gasket 16 are made of rubber or other flexiblematerial, the parts may come together and be separated without noise.After the head aortion 13 of the knob 11 has been projected lnto theouter end of the post 1 as above indicated, it will require the exertionof a pull of more or less force upon the door to cause the head portion13 of the knob 11 to be withdrawn from within the outer end of the saidpost 1, due to the fact that the flange 5 will have contact trictionallywith the side or" the said head 13. Thus the structure performs a doublefunction namely that of a door check and that of a door holder.

The post 1, socket member 8, and knob 11 are preferably made from sheetmetal and may have any desired design or configuration and therefore thestructure as an entirety may present an ornamental and finished aspectwhen applied to a swinging structure and wash-board as indicated.

Having described the invention, what .l claim as new and desire tosecure by Letters Patent is:

1. A door check and holder comprising a post having a hollow endportion, spaced rings formed in the vicinity of the end of said post,the outermost ring being of less diameter than the innermost, a socketmember adapted to receive the end of said post, a knob member located inthe socket member and adapted to be received by said hollow end portionand having a shoulder portion with an adjacent reduced neck portion anda globular end portion and a flexible gasket located in the socketmember and adapted to be engaged by the outermost ring of said post.

2. A door check and holder comprising a post having a slitted hollow endportion provided with an inturned flange, a socket member for saidhollow end portion, a knob located in the socket member and adapted tobe received by said hollow end portion and having a shoulder portionwith an adjacent reduced neck portion and an approximately globular headportion, the diameter of the said head portion of the knob beingslightly greater than the diameter of the opening between the oppositesides of the flange formed at the extremity of the post and a flexiblemember mounted upon the reduced neck portion of said knob.

33. A door cheek and bolder comprising a post having a slitted hollowend portion provided upon its exterior with spaced annular rings, theoutermost one of which is of less diameter than the innermost and havingat its outer extremity an inturned flange, a socket member for saidhollow end portion, a flexible gasket located in the socket member, aknob located in the socket member and adapted to be received by saidhollow end portion and having a shoulder portion with an adjacentreduced neck portion and an approximately globular head portion, aflexible member mounted upon the reduced neck portion of said knob, thediameter of the head of the knob being slightly greater than thediameter of the space between the opposite walls of the flange formed atthe outer end of the post.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
